information that starts on page 6.
Overview of Features
The OptiFiber
®
Pro Optical Time Domain Reflectometer (OTDR)
module attaches to a Versiv and Versiv
rugged, hand-held tester that lets you locate, identify, and
measure reflective and loss events in multimode and single-mode
fibers. Typical maximum test ranges are 35 km maximum at
1300 nm for multimode fiber and 130 km maximum at 1550 nm
for single-mode fiber. The modules include these features:
Automatic analysis of OTDR traces and events helps you
•
identify and locate faults on multimode (850 nm and
1300 nm; 50 μm and 62.5 μm) and single-mode (1310 nm and
1550 nm) fiber.
Shows OTDR results as an intuitive map of events, a table of
•
events, and an OTDR trace.
Automatic bi-directional averaging gives you more accurate
•
loss measurements than measurements made in one
direction.
Gives a PASS or FAIL result based on a test limit that you
•
specify.
"Document Only" test limit is available if PASS/FAIL results are
•
not necessary.
Event editing function lets you edit loss events. See Chapter 9.
•
Span function lets you limit OTDR results to a section of fiber
•
that you define. See Chapter 9.
